SPRING- SCALE.

SPECIFIOATION forming part of Letters Patent No. 505,091, datedSeptember 19, 1893.

Application filed May 11, 1893.

To all whom it may concern:

Be it known that I, GEORGE H. CHATILLON, a resident of the city, county,and State of New York, have invented an Improvement in Spring-Scales, ofwhich the following is a specification, reference being had to theaccompanying drawings, forming part hereof, wherein- Figure 1 is a sideview of a scale with parts broken away, illustrating my invention. Fig.2 is a top view of the same.

My invention relates to spring scales and consists in the arrangementand combination of parts hereinafter described and claimed.

In the drawings a represents a scale beam suitably pivoted upon astandard A. Preferably near one end of this beam to is connected themain spring I) of the scale which may be provided with a suitabletension adjusting device as shown at c. To the beam at, and preferablyat one end thereof, is pivoted a rack bard having a bend or kink 'iwhich takes the rack proper out of line with the pivot. In other words,the pivotj of the rackbar stands beyond the toothed edge of the rack. Tothe opposite end of this rack bar (1 is secured one end of a coiledspring e the other end of said spring being attached to a fixed part ofthe scale, for purposes which will be hereinafter referred to. Gearingwith the rack bar d is a pinion f, the arbor of which Serial No.473,836. (No model.)

carries the hand g adapted to register on the dial it the weight of thearticle placed upon the scale pan.

It will be observed that the spring eactsin a very effective andreliable manner to keep the teeth of the rack and pinion engaged so thatthere will be no lost motion and at the same time so that the leastpossible amount of friction of the parts is had. It will also beobserved that in addition to the above, the spring e relieves the strainupon the main spring, and in some cases said main spring may bedispensed with entirely, a spring e, correspondingly strengthened,acting in its stead and performing its function.

Having thus described my invention, What I claim, and desire to secureby Letters Patcut, is t In a spring scale, the combination of the beama, rack-bar (1, one end of which is pivoted to said beam, pinion fmeshing therewith, and coiled spring 6 connected to the free end of saidrack bar and to a stationary part of the scale, whereby said springeexerts a resistance against the scale beam 0. and

holds the rack bar in engagement with the pinion, substantially asdescribed.
